this study was aimed to investigate the effect of altitude on fiber characteristics, chemical composition and kraft yield pulp of brutian pine. wood samples were collected from different altitudes as 450, 750 and 960m of arabdagh plantation, located in kalaleh region in the northeast of golestan province. three healthy sample trees of brutian pine were cut from each altitude. maceration of earl...

Ternary Content-Addressable Memories (TCAMs) provide a fast mechanism for IP lookups and a simple management for route updates. The high power consumption problem can be resolved by providing a TCAM partitioning technique that selectively addresses smaller portions of a TCAM. This paper proposes a 2-level TCAM architecture using prefix comparison rule to partition the routing table into a numbe...

Ruta species are known as a potential source of natural products with biological activities. They are used in several fields such as in therapeutic and traditional medicine. In order to contribute to the valorization of these plants, this work investigated the chemical composition and antibacterial activity of the essential oils of Ruta montana and Ruta gravelons growing in tunisia (north o...

structural properties and chemical composition change the photocatalytic activity in tio2-sio2 nanopowder composite. the sio2-tio2 nanostructure is synthesized based on sol–gel method. the nanoparticles are characterized by x-ray fluorescents (xrf), x- ray diffraction (xrd), tunneling electron microscopy (tem), field emission scanning electron microscopy (fe-sem), uv-vis. spectrophotometer and ...

To study any science and to master a certain profession, it is necessary acquire the language way of thinking that science. Chemistry has its own made up chemical symbols, nomenclature, terminology, it's which serve as keys,methods, tools for chemistry. Therefore, in order chemistry-based fully language, theory- methodology teaching are one issues should be studied by chemistry teachers researc...

this research, for lowering the use of chemical fertilizer, was carried out using combinations of biological and chemical fertilizer on bean in rasht region in 2012 growing season. the experiment was conducted based on randomized complete blocks design with 12 treatments and three replications. experimental treatments included: control (no fertilizers and no inoculants), chemical fertilizers (n...

Ternary content-addressable memory (TCAM) has been widely used to perform fast packet classification due to its ability of solving the problem in O(1) time without considering the number of entries, mask continuity and their lengths. However, it also comes with several shortcomings, such as the limited number of entries, expensive cost and power consumption. We propose an efficient algorithm to...

The Need Two lines of evidence are converging to indicate that control software will be one of the key areas in which further progress must be made before practical magnetically confined fusion energy will be a reality. The first of these is lines of evidence is the observation that progress in the field of fusion energy has been so great that the temperature and density requirements needed for...

Ternary content addressable memory (TCAM) is one key component in high-performance networking applications. An asymmetric TCAM cell consists of a binary content addressable memory (BCAM) bit and a mask bit. In this paper, we analyze comparison faults of the asymmetric TCAM cell based on BCAM comparison faults. Then march-like test algorithms T are proposed to cover the comparison faults of the ...
